for New Directions to win, and has agreed to end her blackmail of Principal Figgins in exchange for giving New Directions at least one more year to prove themselves and win Regionals. She explains to Will that she may not like him, but she respects his work with the students. Will tells the club of its extension, and performs Israel Kamakawiwoʻole's version of "Over the Rainbow" with Puck in celebration. Production "Journey to Regionals" was filmed in April 2010, with fans of Glee invited through Facebook and Twitter to attend the filming of Regionals at the Saban Theatre in Beverly Hills, California. In the episode, both Josh Groban and Olivia Newton-John reprise their roles from earlier in the season, appearing as themselves to judge the Ohio Regionals round of show choir competition alongside Sue and Rod Remington. Series creator Ryan Murphy explained: "The theme of Regionals is celebrity judges. Sue is now a nationwide celebrity. And Olivia and Josh only like choirs that sing their songs, so that's funny. They wanted to do something that played against what people think about them... to play against type. So we gave them an opportunity. And it's funny to have Sue as a judge when she doesn’t really know about [music], and she has it out for that darn Glee club." Other recurring characters who appear in the episode are glee club members Santana Lopez (Naya Rivera), Brittany (Heather Morris), Mike Chang (Harry Shum, Jr.) and Matt Rutherford (Dijon Talton), Principal Figgins, Vocal Adrenaline lead singer Jesse St. James (Jonathan Groff), Vocal Adrenaline coach and Rachel's birth mother Shelby Corcoran, and Quinn's mother Judy Fabray. Emma's new love interest does not appear in the episode, but will become a major character from early in the show's second season, played by John Stamos. Will and Emma's kiss in "Journey to Regionals" was unscripted. Falchuk chose not to inform Mays that it was planned to ensure authenticity in her reaction. Glee: The Music, Journey to Regionals, an EP containing songs from the episode, was released on June 8, 2010. It features cover versions of Journey's "Faithfully" and "Don't Stop Believin'", as well as a mash-up of "Any Way You Want It" and "Lovin' Touchin' Squeezin'". "Bohemian Rhapsody" by Queen is also on the EP, as is "To Sir With Love" by Lulu and Judy Garland's "Over the Rainbow" as reinvented by Israel Kamakawiwoʻole. The EP
